Although we have a short time until Harvest, there are still some tricks you can use to increase your yield this season. Make sure you are focusing on increasing your feeding/nutrients to ensure your plants are capable of producing the largest colas possible. Supporting your plants and pruning are essential to proper airflow, which will allow your plant to direct energy where it is needed the most. Lastly, mold scouting should be a major priority at this time. Read on for the breakdown of each of these tips.
Feeding/Nutrient Boosts for Big Yields:
What we feed ourselves plays a major role in how we grow, and the same goes for our plants and their ability to produce a heavy yield. This is the time of the season for heavy feeding, but you don’t want to just hit your plants with high levels of nutrients at the end of their flower cycle. Every week growers should build up the nutrient levels rather than dramatically increase at the end as this could lead to nutrient burn.
The three main nutrients your flowering plants need are nitrogen, phosphorus, and potassium, with the majority of that need being Nitrogen. Compost teas are a great way to give your ladies a wide range of nutrients, microorganisms, and enzymes. Add molasses (unsulfured is the best quality), a carbohydrate, in the last couple weeks before you flush, to get a top quality end product. Also, sure you are giving yourself about a week to flush your plants prior to harvesting. See our Cultivation Resource for Watering for more information.
Support Your Plants to increase yield
Supporting your plants is not only crucial to your plant’s growth, but it will also help to increase your yield at harvest time. Bamboo stakes (or metal stakes) and trellising (or cages) are important things to start your garden when your plant is young, but you will find these items most useful once she begins producing buds. Supporting your plant is a continuous process as the plant grows and the supports will often need to be adjusted throughout her growth cycles.
As the buds grow, you will need to support them with additional stakes or trellis netting. This not only will help support the branches holding heavy buds, but it also helps to train the plant’s growth. When cultivating outdoors one must always be in anticipation of the late season rain because rain will often knock down plants that are not properly supported.
Pruning for Yield:
Pruning is the act of defoliating the plant to allow for more airflow, more light to necessary parts of the plant and to simply training and supporting processes. This can occur throughout the veg and flower cycle, but is most important during her flowering cycle. Most importantly, you want to be pruning low hanging branches that are not likely to receive much light, dying leaves and lower bud sites that are not receiving much light at all (ones on main stalk). When it comes to pruning for the increase of airflow through the plant you want to completely clean out the bottom 1/3 of the plants, and anything in the center that isn’t getting any light.
Minimize Chances of Bud Rot to protect your yield:
Bud rot or mold can take over your entire crop, and quickly, so it is important to take the necessary precautions to prevent those issues from occurring. These precautions include necessary airflow, warmer temperatures, lower humidity and keeping an eye out for mold.
Optimal airflow for your plants can be achieved by strategically placing fans around your enclosure (greenhouse, indoor), or by properly pruning your outdoor plants to allow air to flow through it efficiently. Warmer temperatures and lower humidity can be achieved by keeping your buds away from as much moisture as possible. Covering them when it rains is one of the best ways to avoid moisture.
Lastly, you want to constantly be scouting for mold. If you see it, remove that bud and any neighboring buds, or it will spread throughout your crop. Also, be careful of overwatering, with the days becoming shorter and are not as hot, this will increase the time it takes your plants to dry out and can lead to molding. Some growers suggest using a beneficial streptomyces foliar spray, known as Forge (by Blacksmith Bioscience), once a week to prevent powdery mildew and insects during those last few weeks of flower. **Always add a wetting agent such as “Coco Wet” when using a foliar spray.
